Installing a solar hot water system using an Suntimes solar collector, is a simple upgrade that homeowners can make to protect themselves from rising energy costs.

An Suntimes solar hot water system can provide between 50-90% of a households annual domestic hot water FREE from the sun making it one of the most effective ways to save money on your energy bill and also reduce your household’s carbon footprint.

When comparing peak efficiency levels it may seem that there is little difference between flat plate and evacuated tubes, in fact flat plate may actually be higher, but this is during minimal heat loss conditions. When averaged over a year evacuated tube collector have a clear advantage. The key points are:
1). Due to the cylindrical shape of the evacuated tube, the solar tubes are able to passively track the sun throughout the day. Flat plate collectors only provide peak energy output at midday when the sun is perpendicular to the collector's surface. To learn more about IAM and performance click here.
2). Air is evacuated from the solar tube to form a vacuum. This greatly reduces conductive and convective heat loss from the interior of the tube. As a result wind and cold temperatures have less effect on the efficiency of the evacuated tube collector.
3). Suntimes solar collectors can often be used in subzero temperatures without the system sustaining damage. Flat plate systems often require expensive and complicated "antifreeze" systems to be installed.
4). Evacuated tubes are strong, long lasting, and should one be broken, inexpensive and easy to replace. If a flat plate collector panel is damaged the whole panel must be replaced.
5). Due to the high efficiency absorption of solar radiation even during overcast conditions, combined with excellent insulative properties of the solar tube, solar tube collectors can heat water all year round (backup from gas and electricity is still required).
6). Due to the various advantages of evacuated tube collector over flat plate collectors, a smaller collector can be used to provide the same heating performance. For example, a standard household of 4-5 people would usually require a 250-300L water storage tank. Depending on your location, only 30 evacuated tubes would be required to provide all summer hot water needs and a large percentage in other seasons.
7). Flat plate solar collectors can produce similar heat output to evacuated tube collectors, but generally only during hot, sunny conditions. When averaged over an entire year, evacuated tube collector heat output per net m2 of absorber area, is between 25% to 40% greater that a flat plate collector.

3.Why use Heat pump water heater?
Many place sunlight is not rich all year,or the building is no space for install solar water heater.
Such as:Apartment,Balcony.
The case install Heat pump water heater is best choice,because heat pump no need much installation space,no need sunlight.It can install on roof,balcony or wall.
Suntimes air source heat pump water heater,collect energy from ambient.
Compressor compressor refrigerant,it use electricity to carry energy from low to high,not use electricity to make energy.
It can save75% to 80% electricity,compare with traditional electrical water heater.
